DOOR.

Application filed May 4, 1917.

' door may be forced into a door opening and seated firmly against a rabbeted janib so as to lie flush with the outside of the build ing or other structure when in closed position. The invention seeks to attain the desired object by means which will be simple, inexpensive, efficient and easily operated.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective view of a traveling door having my improvements embodied therein;

Figs. 2 and 3 are vertical sections showing the door in open and closed positions respectively;

Fig. 4: is a horizontal section on the line 4[4 of Fig. 2;

Fig. 5 is a detail perspective view of the track hanger and the door member or bracket cooperating therewith.

In the accompanying drawings, the invention has been shown applied to a rolling barn door but it is to be understood that it is applicable to car doors and all other forms of sliding or rolling doors and that the invention is not limited in its scope to the single embodiment illustrated.

In the drawing, 1 indicates a portion of a barn or other structure and 2 a door jamb fitted therein and provided with a rabbeted edge 3. A track .L is secured to the side of the structure above the door opening and extends longitudinally of the building in the usual manner. The track is illustrated in the present drawings as consisting of a grooved rail supported by brackets 5 secured in the wall. Rollers 6 are mounted to travel in or on the track and these rollers are journaled at the upper ends of hangers 7 which depend from the journals of the rollers and are offset therefrom so as to clear the track and pass below the same. The lower ends of the hangers are con- Specification of Letters Patent.

structed with outwardly projecting lateral lips or flanges 8 in which are formed longitudinal slots 9 which have their inner walls coincident with the outer surfaces of the upright portions of the hangers, as clearly shown in Fig. 5. Other longitudinal slots or angular openings'lO are formed in the upright portions of the hangers above the said lateral lips or flanges, as shown. To the outer side of the door 11, at the upper end thereof, I secure the door brackets 12 which consist each of a base plate rigidly secured to the door, an upper arm 13 extending from the base plate and of a cross sectional form corresponding to the opening 10 in the hanger 7 so that the said arm may project through said opening and slide therein, but will be prevented fronrrotating therein, and a lower arm 14. which is shorter than the upper arm and is provided with a circular opening or bearing 15 near its outer end. Other bearing brackets 16 are secured to the outer side of the door below the upper brackets and rock shafts 17 are mounted in the said bearing brackets and in the openings 15 of the arms 14., as clearly shown. These rock shafts may be prevented from dropping by any convenient or preferred means and to the upper ends thereof, I secure the cranks 18 having pins or fingers 19 at their free ends adapted to play in the longitudinal slots 9 of the hangers 7. Suitable handles 20 are provided at the lower ends of the rock shafts so as to facilitate their manipulation in the operation of the door.

It is thought the operation and advantages of my improved door mounting will be readily understood from the foregoing de scription taken in connection with the accompanying drawings. \Vhen the door is seated in the rabbets 3, the crank arms 18 will project outwardly, as shown in Figs. 1 and 2. The cranks, lying at a right angle to the length of the slots 9, will form braces so as to press the door to its seat and resist any tendency of the same to swing outwardly. If it be desired to open the door, the shafts 17 are rocked so that the cranks 18 will. swing or turn toward the door. The pins or fingers 19 at the outer ends of the cranks will then be permitted to ride longitudinally of the slots 9 but cannot swing inand the upper door brackets so that the door,

will be withdrawn from its seat and will clear the slde of the bulldin'g or other structure, as shown in Fig. 3, after which it may be moved along the track 4 in the usual manner. I

It will be readily noted that the device is exceedingly simple in the construction and arrangement of its parts. The door will be firmly supported and when in closed position will be positively held to its seat so that it will not be apt to work loose under high winds or other causes. The engagement of the arms 13 on the upper door brackets with the track hangers is such that the door will be caused to move in a rectilinear path to and from the door opening and damage to the door frame or the sides of the door will thus be avoided.

Having thus described the invention, what is claimed as new is:

1. The combination of a door a track, hangers adapted to travel longitudinally of the track and provided at their lower ends with lateral lips having longitudinal slots and provided above said lips with transverse openings, suspending members secured to the door and having upper. arms projecting through said transverse openings in the hangers and lower arms projecting toward and below the hangers, brackets onthe door below said suspending members rock shafts mounted in said brackets and the lower arms of the suspending members, and crank arms on the upper ends of said rock shafts provided at their free ends with pins engaging the longitudinal slots in the lipsat the lower ends of the hangers.

2. The combination of a door, a track, hangers adapted to travel on the track and provided at their lower ends with lateral lips having longitudinal slots and provided above said lips with transverse openings, suspending memberssecured to the door and having upper arms projecting through and slidable in the transverse openings in the hangers and lower arms projecting toward and below the hangers, and crank shafts mounted in the lower arms of the suspending members and having their cranks engaging the longitudinal slots in the hangers.

In testimony whereof I affix my signature.
